Where is SCADA used? SCADA can be used to manage many kinds of equipment. Typically,
SCADA systems are used to automate complex industrial processes where human control is impractical.
Manufacturing: Buildings, facilities and environments: Electric power generation, transmission and distribution: Water and sewage: Mass transit: Traffic signals: SCADA regulates traffic lights, controls traffic flow and
detects out-of-order signals.

SCADA/HMI building automation system advantages
Using SCADA platforms for your building automation system allows you to get exactly the features and capabilities you want now and in the future as your needs grow.
SCADA systems are powerful, robust and flexible.
SCADA is robust Manufacturers, water treatment and other operations have been relying for decades on SCADA systems to control their processes.
![Page 11: All about scada](https://reader036.fdocuments.net/reader036/viewer/2022081507/55547ae2b4c90548358b48de/html5/thumbnails/11.jpg)
Integratability Over the years, users have demanded that SCADA system developers
enable connectivity with the unlike systems and networks with their plants.
This openness is highly beneficial for building automation systems with the many diverse component systems to be integrated.
Flexibility SCADA systems are scalable and upgradeable.
Reporting Which reports do you want where at what time? Want to see status on
all your systems from any web browser anywhere, even from your smartphone?
With SCADA, you can do it. As you can also, if you chose, enable control over remote connections.

Communication and software
The SCADA consist of Hardware and Software components.
The hardware collects and feed data into a computer with SCADA software installed.
The data is then processed by the computer before presenting it in a timely manner.

A Programmable Logic Controller (PLC) or Remote Terminal Unit automatically performs the main site control process.
The host control functions in most cases are limited to the capability of supervisory level or site override.

Data Acquisition begins at the RTU or PLC level and includes meter readings and equipment status reports that are communicated to SCADA as required.
Data is then compiled and formatted in such a way that a control room operator using the HMI can make supervisory decisions to adjust or override normal RTU (PLC) controls.

What is RTU?
An RTU monitors the field digital and analog parameters and transmits data to the Central Monitoring Station. It contains setup software to connect data input streams to data output streams, define communication protocols, and troubleshoot installation problems.
An RTU may consist of one complex circuit card consisting of various sections needed to do a custom fitted function or may consist of many circuit cards including CPU or processing with communications interface(s), and one or more of the following: (AI) analog input, (DI) digital input, (DO/CO) digital or control (relay) output, or (AO) analog output card(s).

RTU
a microprocessor-controlled electronic device that interfaces objects in the physical world to a distributed control system or SCADA (supervisory control and data acquisition) system by transmitting telemetry data to a master system, and by using messages from the master supervisory system to control connected objects.
Another term that may be used for RTU is remote telemetry unit, the common usage term varies with the application area generally.

Single board RTU
which is compact, and contains all I/O on a single board. The single board RTU normally has fixed I/O (eg.16 digital inputs, 8 digital outputs, 8 analogue inputs, and say 4 analogue outputs).
![Page 35: All about scada](https://reader036.fdocuments.net/reader036/viewer/2022081507/55547ae2b4c90548358b48de/html5/thumbnails/35.jpg)
Modular RTU
which has a separate CPU module, and can have other modules added, normally by plugging into a common "backplane" (a bit like a PC motherboard and plug in peripheral cards) is designed to be expanded by adding additional modules.

RTUs differ from programmable logic controllers (PLCs) in that RTUs are more suitable for wide geographical telemetry.
RTUs, PLCs and DCS are increasingly beginning to overlap in responsibilities, and many vendors sell RTUs with PLC-like features and vice versa.
In addition, some vendors now supply RTUs with comprehensive functionality pre-defined, sometimes with PLC extensions and/or interfaces for configuration.
Some suppliers of RTUs have created simple graphical user interfaces GUI to enable customers to configure their RTUs easily. In some applications data loggers are used in similar applications.

FUTURE TRENDS IN SCADA
First generation: "Monolithic“
Second generation: "Distributed“
Third generation: "Networked"
![Page 43: All about scada](https://reader036.fdocuments.net/reader036/viewer/2022081507/55547ae2b4c90548358b48de/html5/thumbnails/43.jpg)
First generation: "Monolithic"
In the first generation, computing was done by mainframe computers.
Networks did not exist at the time SCADA was developed.
Thus SCADA systems were independent systems with no connectivity to other systems. Wide Area Networks were later designed by RTU vendors to communicate with the RTU.
The first-generation SCADA system was redundant since a back-up mainframe system was connected at the bus level and was used in the event of failure of the primary mainframe system.

Second generation: "Distributed"
The processing was distributed across multiple stations which were connected through a LAN and they shared information in real time.
Each station was responsible for a particular task thus making the size and cost of each station less than the one used in First Generation.

Third generation: "Networked"
Due to the usage of standard protocols and the fact that many networked SCADA systems are accessible from the Internet, the systems are potentially vulnerable to remote attack.
